Flashes of light on the dark matter

Through simulations carried out with supercomputers, researchers reproduced the interaction of the light with the cosmic web. Thus they were able to infer some of the characteristics of the particles that compose the dark matter. Their results have been published in Physical Review Letters.

Shedding light on galaxy rotation secrets

/ Phys.org

Spiral galaxies are found to be strongly rotating, with an angular momentum higher by a factor of about 5 than ellipticals. An international research team investigated the issue in a study just published in the Astrophysical Journal.

Shedding Light on Galaxies' Rotation Secrets

/ R&Dmag

Spiral galaxies are found to be strongly rotating, with an angular momentum higher by a factor of about 5 than ellipticals. The researchers from SISSA (Trieste), USTC (Hefei) and IRA-INAF (Bologna) inferred from observations the amount of gas fallen into the central region of a developing galaxy, where most of the star formation takes places.
